It's super neat! Just like Kubernetes is also super neat at what it can do. It's super neat primarily because consuming it is so easy, provided you already have all the same abstraction layers in place in your infra.

You...do have all the same abstraction layers, right? No? Oh. Well, don't worry, Google/Amazon/Microsoft can sell you those if you don't want to pay your IT staff to prop it up for you.

Look, snark aside, yours is the correct take. Google's solutions are amazing, but they're also built for an organization as large and complex as Google. Time will tell if this is an industry-standard abstraction (a la S3 APIs) or just a Google product for Google-like orgs/functions (a la K8s).
